2 '0 all 20 ham it may concern:

Be it known that we, TVILLIAM F. Boxcar and Hammer V. CoULsroN, citizens of the United States, residing at- Philadelphia, Pennsylvania,v have invented certain Tmprovcmeirts in Garnett Machines, of which tie following is a specification.

Our invention relates to certain improvements in Garnett machines.

Gne object of the invention is to provide a series of separate plates, or shoes, which are secured to the arch of a Garnett machine and on which the poppets are adjustably mounted so as to provide means for adjusting the rolls on account of variations in the diameter of said rolls.

A further object of the invention is to make the adjustable plates of struck up sheet metal. Heretofore. it has been the general practice in manufacturing Garnett machines to form the projections, or lugs, as abutments for the lateral adjusting screws and as a. bearing for the longitudinal adjusting screws integral with the arch. By having the separate plates, the plates can be adjusted and held in the position to which they are adjusted. In the event of breakage, one plate can be detached and another plate substituted for it.

In the accompanying drawings:

Figure 1 is a side view of sufiicient of a Garnett machine to show a portion of the arch and the plates secured thereto;

Fig. 2- is a sectional view on the line 2-2, Fig. 1; i

Fig. 3 is a perspective view of one of the detachable plates;

Fig. 1 is a. perspective view showing the rear of the plate illustrated in Fig. 3;

Fig. 5 is a view of one of the'fixed nuts for the reception of the longitudinal adjusting screw; and j Fig. 6 is a view of a blank from which the plates are made.

1 is the arch of a Garnett machine. 2 are the detachable segmental. plates, which are secured to the arch by the bolts 3 and nuts 41, as clearly shown in Fig. 2. These bolts pass through holes 5 formed in the plates 2 and they are of a sufficient length to retain a poppet 6 to the plates by means of the nuts 7. The poppet supports the bearing 8 for the shaft 9, on which is mounted one of the small rolls 10 of a Garnett machine. These rolls partially surround the main cylinder 11, shown by dotted lines, and are provided with garnett teeth in the ordinary manner. The plates 2, in the present instance, are struck up from sheet metal. Each plate has two projections 12 at the upper end and two projections 13 at the lower end. The projections 12 actas abutments for the set screws 14, which extend through the flanges 15, and, on turning these set screws, each poppet can be laterally adjusted. The lower projections 13 are cut to receive the fixed nuts 16 through which the longitudinal adjusting screws 17 extend. These adjusting screws have flanges 18 and 19 spaced apart and a forked projection 20 of the poppet extends between the two flanges 18 and 19. The adjusting screw has a head 21, on turning which the poppet can be longitudinally adjusted.

While the plates may be made in any manner desired, we prefer to make them of sheet metal, or bend them from a fiat plate punched, as shown in Fig. 6, which, after being punched. is bent into shape, as shown in Fig. 3. We may place filling blocks 22 in the recesses of the projections 12, if found desirable. If the plates are made of comparatively heavy, metal, the filling blocks are unnecessary.

The nuts 16 are made as shown in Fig. 5 and are cut. away at 23 forming lugs 24, which extend on each side of the projections 13, the projections being cut to receive the lugs. This makes a very rigid construction 1 and one which will allow for the ready adjustment of the individual poppets, as well as the adjustment of each pair of poppets.

When it is desired to adjust any of the plates, this can be accomplished by de taching the nuts 7 to remove the poppet and loosening the nuts 4- to allow for the adjusting of the plates. plifies the manufacture of a Garnett machine, as, instead of the complicated casting heretofore required to form an arch, a plain one, can be used to which the plates are secured.

Furthermore, the poppets can be adjusted on the plates without loosening the plates.

We claim: 1. The combination in a Garnett machine, of an arch; a series of plates mounted on This construction sim- V the face of the arch, said plates having pro-Q jections; poppets mounted on the plates; bolts extending through the plates and through the poppets; and two nuts on each bolt one holding the plate to the arch aiiei the other holding the poppet to the plate and to the arch.

2. The combination in a G'ai'nett machine, o1 an arch; a series of plates secured to the arch, each plate having two sets of projec- '10 tions; a hole between each set of projections;

fixed nut held by each oi the lower proections; ad usting screws passlng through the l'llltS; poppets having pro ect1ons engagingthe ad usting screws and havlng set screws hearing against the upper PI'OJGC- tions, the set screws adjusting the poppets laterally the other screws adjusting the poppets longitudinally.
